This process is separate from the sequential system as it produces a fixed 3D marking that can be used on batches of product. The marking can again be used on product and packaging giving a secure link between the items. The marking has a number of levels of security. It can be as small as 0.5mm diameter but at the same time contains a number of different heights that are so small the marking, if seen, looks like a printed image.

This impression is 1 mm in diameter containing heights of 3, 6 and 9m.
The marking can be one chosen by the client, for example the company logo producing a bespoke fingerprint. The heights within the marking can be periodically changed to further increase security.
